Wenger says his current centre-back options remind him of when Tony Adams, Martin Keown and Steve Bould were all in the Arsenal squad.
"Yes, it is a bit like that," he told Arsenal Player. "The one who didn't play [the decision] was not justifiable.
"In the end we played the three together in some games, but when I moved to a back four we were always in a position where you had to make a choice.
"I rotated and at some stage every time I made a decision [about who] was left out, I thought 'it is not right'."
